A
typical Fresnel Lens is made up of many small narrow concentric rings.
Theoretically speaking, each ring can be considered as an individual
small lens that bends the light path.

In fact, the curvature in each ring is approximated by a flat surface so that each ring behaves like an individual wedge prism:

The
advantage of using a Fresnel lens is its compact size compared with a
conventional lens. Common usage includes overhead projectors,
pocket-size magnifiers and motion detectors. The word "Fresnel" comes
from the person who first used this design to construct lighthouse
lenses, Augustin-Jean Fresnel, in 1820. The idea of dividing a lens
surface into concentric rings in order to reduce weight and size,
however, can be dated back to 1748 by Georges-Louis Leclerc.

Fresnel
Lenses can be made from plastic or glass. There are also different
design variations such as Positive Fresnel Lens, Negative Fresnel Lens,
Cylindrical Fresnel Lens, Fresnel Lens Array, Linear Fresnel Lens,
Lenticular Lens and Fresnel Prism.

The
following table lists the standard Fresnel lenses that AWI supplies.
Custom-made Fresnel lenses are also available. Fresnel lenses can also
be cut to specific sizes as requested.

AWI
Industries (USA) Inc. supplies a series of specially designed Solar
Energy Collector Fresnel lenses. The difference between a Solar Energy
Collector fresnel lens and a standard Fresnel lens is that the Plano
side (smooth side) of all Solar Energy Collector Fresnel lenses is
facing the sun. Apart from standard Fresnel lenses, AWI Industries
(USA) Inc. also supplies Fresnel lenses made to customers' designs with
reasonable custom tooling charges.

Glass Fresnel lenses-AWI Industries (USA)
Inc's standard glass Fresnel lenses are made of borosilicate glass
material to provide better mechanical strength and resistance to
thermal shock. These glass Fresnel lenses are widely used in the
theatre lighting, architectural lighting, movies lighting, signal
lighting as well as other industrial lighting applications.
